Shape modelling reveals age-related knee bony shape changes in asymptomatic knees.

Osteoarthritis (OA) causes bony shape changes within the knee. Furthermore, the risk of developing OA increases with age. However, age alone does not cause OA. It is therefore important to understand the healthy age-related trajectories of knee shape before attributing these changes to OA. The aim of this study was to determine the association between bony knee shape and age using statistical-shape modelling (SSM). 96 participants received a CT scan of their knee. Three-dimensional models were created using manual segmentation. Separate SSM's for the distal femur and proximal tibia were created. Linear regression models were used to assess the association between age and femoral and tibial shape. Fourteen modes of the femoral and tibial SSM's captured 68% and 73% shape variation, respectively. Only femoral mode 3 and tibial mode 7 were associated with age. Increasing age was related to larger femoral bone volume and deepening of the femoral trochlear groove. Furthermore, increased age was associated with medial tibial plateau expansion. Aspects of bony femoral and tibial shape were significantly associated with aging, including femoral and tibial bone size, femoral trochlear groove, and medial tibial plateau area. Changes in knee morphology occur as a normal process of aging without osteoarthritis development. This may be a response to mechanical loading over time. Further research investigating the effect of these changes on loading in the knee may provide valuable information for knee health in older age.

Sex differences in the impact of lower respiratory tract infections on older adults’ health trajectories: a population-based cohort study

BackgroundLower respiratory tract infections (LRTIs) are a major global health concern, particularly among older adults, who have an increased risk of poorer health outcomes that persist beyond the acute infectious episode. We aimed to investigate the mid-term (up to 7 years) and long-term (up to 12 years) effects of LRTIs on the objective health status trajectories of older adults, while also considering potential sex differences.MethodsCohort data of adults aged ≥ 60 years from the Swedish National study of Aging and Care in Kungsholmen (SNAC-K) collected between 2001 and 2016 was analyzed. Information on LRTIs was obtained from the Swedish National Patient Register, and objective health status was assessed using the Health Assessment Tool (HAT) which incorporates indicators of mild and severe disability, cognitive and physical functioning, and multimorbidity. The LRTI-exposed and -unexposed participants were matched using propensity score matching based on an expansive list of potential confounders. Mixed linear models were used to analyze the association between LRTIs and changes in HAT scores.ResultsThe study included 2796 participants, 567 of whom were diagnosed with a LRTI. LRTIs were independently associated with an excess annual decline of 0.060 (95% CI: -0.107, -0.013) in the HAT score over a 7-year period. The associations were stronger among males, who experienced an excess annual decline of 0.108 (95% CI: -0.177, -0.039) in up to 7-years follow-up, and 0.097 (95% CI: -0.173, -0.021) in up to 12-years follow-up. The associations were not statistically significant among females in either follow-up period.ConclusionLRTIs, even years after the acute infectious period, seem to have a prolonged negative effect on the health of older adults, particularly among males. Preventative public health measures aimed at decreasing LRTI cases among older adults could help in preserving good health and functioning in old age.

Comparing the Health Status of Immigrant and New Zealand-Born Older Adults in Aotearoa New Zealand: The Role of Socioeconomic Position.

The study investigated the health status of older migrants relative to their New Zealand-born peers. We adopted a holistic view of health (physical, mental, and social) and a structural approach to health disparities based on migrant status and socioeconomic position. Using case-control matching based on age, gender, and education, the health status of 357 older migrants and 357 New Zealand-born older adults was compared. Older migrants reported significantly poorer social health. Health inequities were patterned by socioeconomic status. Working class older migrants had significantly poorer physical, mental, and social health than their New Zealand-born peers. Inequities in social wellbeing persisted even at the upper end of the social gradient. Migrant background is an important social determinant of health in older age. The reduced social wellbeing of economically advantaged migrants highlights vulnerabilities regardless of socioeconomic position and the need for targeted social policies.

Narrative review: nutritional strategies for ageing populations - focusing on dysphagia and geriatric nutritional needs.

The increase in elderly populations worldwide highlights the urgency of addressing age-related problems through effective nutritional management to enhance the well-being of the elderly and for the prevention and treatment of various diseases. The trend towards an increasing elderly population brings with it an increase in conditions such as sarcopenia, osteosarcopenia and frailty, emphasising the importance of regular checks for malnutrition in the elderly and the implementation of personalised nutritional therapies. The importance of nutrition in addressing geriatric syndromes such as frailty, sarcopenia, osteosarcopenia, obesity and metabolic syndrome is highlighted. Dysphagia, frequent in the elderly, requires special attention to prevent malnutrition and complications. It is essential to maintain muscle mass and bone health in old age. In this review we investigate the fundamental role of nutrition in geriatrics, focusing on promoting healthy ageing and managing problems such as malnutrition and overeating. The importance of protein intake and healthy dietary patterns such as the Mediterranean diet are then discussed. Finally, the challenges of personalised nutritional care, including the need for artificial nutrition or oral supplements, to improve quality of life and health care in an ageing society are addressed.

The relationship between childhood SES and health in middle and old age: evidence from China.

Drawing from the extended Grossman health capital and demand theory and the life course theory, this study examined whether childhood SES has direct and significant correlation with health in middle and old age in a specific historical context in China. A sample of 9,861 respondents was obtained from the China Health and Retirement Longitudinal Study (CHARLS). Childhood SES was measured by objective indices of recall. Health was assessed by self-reported, physician diagnosis and the Center for Epidemiologic Studies Depression Scale (CESD). The Propensity Score Matching (PSM) was used to estimate the treatment effect between childhood SES and later life health. The Karlson-Holm-Breen (KHB) method was employed to examine the associative mediation effects. Compared to respondents with low SES in childhood, respondents with high SES in childhood had, on average, 5.1% more likely to report their health as good, an average 2.4% lower prevalence of chronic diseases and an average 7.6% lower in the score of depression in middle and old age. The indirect relationships of childhood health, adulthood SES and adulthood lifestyle with health in middle and old age were all significant. SES upward mobility in adulthood can diminish the association between childhood disadvantage and poor health in middle and old age. The health effects of childhood SES can persist into middle and old age, this is more noticeable in rural areas, particularly in females. The critical period, cumulative risk and social mobility models produce synergistic effects in China. Our results also promote a paradigm shift in health interventions from old age to early life for health-vulnerable populations.

Older and heavier: How obesity is experienced by older adults?

ABSTRACT The interplay between obesity and mental health in old age is complex and widely impacted by different biological, psychological, and social factors. The primary objectives of this qualitative research study are: a) To explore the influence of obesity on older adults’ well-being; b) to understand emotional experiences related to obesity in old age and; c) to explore how obesity influences the mental health of older adults. This study included 692 participants aged 65 to 84 years (M = 73.9; SD = 5.61) from three different nationalities (English, Spanish, and Portuguese). The study involved in-depth interviews conducted via telephone or online, with questions designed to elicit detailed narratives about participants’ experiences, and the data were analyzed using content analysis to identify key themes and patterns. This study identified four main themes regarding the influence of obesity on older adults’ well-being: (1) Body image dissatisfaction (66%); (2) Fat shaming (65%); (3) Increased isolation (57%); and (4) Loss of opportunities (46%). Three main themes for emotional experiences were frequently verbalized by the participants: (1) Shame (81%); (2) Guilt (78%); and (2) Worthlessness (76%). Finally, three main influences in mental health due to obesity were reported: (1) Self-esteem (88%); (2) Distress (78%); and (3) Depression (63%). These results highlighted that obesity negatively influences older adults’ well-being and emotional experiences and has serious mental health-related negative outcomes for older adults. Interventions like community-based weight loss programs can be effective in controlling weight and improving the social interaction of obese older adults.

Major clinical outcomes of nutrology and lifestyle in the metabolic processes of healthy aging: a systematic review

Introduction: Centenarians exemplify the concept of healthy aging and therefore provide an invaluable resource for identifying novel host-intestinal microbiota relationships concerning aging. Approximately 18 micronutrients, composed of minerals and vitamins, facilitate the optimal utilization of macronutrients through their role in catalyzing numerous biochemical processes, increasing their bioavailability and absorption, and balancing the microbiome. In the context of aging, a major challenge to maintaining health in old age is unbalanced nutritional intake, resulting in nutritional deficiency or malnutrition. Objective: The main clinical outcomes of nutrology and lifestyle in the metabolic processes of healthy aging were listed through a systematic review. Methods: The systematic review rules of the PRISMA Platform were followed. The search was carried out from July to August 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 118 articles were found. A total of 39 articles were fully evaluated and 29 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 21 studies with a high risk of bias and 15 that did not meet the GRADE and AMSTAR-2 criteria. Most studies showed homogeneity in their results, with X2=82.7%>50%. Zinc and copper govern many functions that characterize the so-called “oxy-aging”. Selenium (Se) is a fundamental cofactor in many redox functions, the role of vitamin C in aging has been investigated particularly for skin health and immunity, particularly in inflammatory and degenerative diseases. Retinoids, which represent a synthetic form of vitamin A, appear effective in preventing skin degeneration due to aging. The role of vitamin E in the prevention and reduction of ROS-induced lesions has been well described. Supplementation with selenium and coenzyme Q10 influenced the analyzed biomarkers in a way that indicated an anti-aging effect. It was concluded that an adequate plasma level of trace elements, such as Zn or copper (Cu), promotes an optimal function of the immune response. Selenium (Se) is a key cofactor in many redox functions, which reduces ROS-induced degeneration in the senescent phenotype. The role of vitamin C in aging has been investigated particularly for skin health and immunity, particularly in inflammatory and degenerative diseases. Vitamin A acts in the prevention of skin degeneration due to aging. The role of vitamin E in the prevention and reduction of ROS-induced lesions has been well described, as well as it has been associated with the prevention of cognitive decline during senescence, particularly in Alzheimer's disease. Good fats, vitamins, minerals, or polyphenols can have antioxidant and anti-inflammatory activities, with anti-aging effects. Recent studies have shown that vitamin K is a vital cofactor in the activation of several proteins, which act against age-related syndromes.

Development of a self-assessment tool to address the functioning of community-dwelling older adults in general practice: a validation study of the EFA23 questionnaire

BackgroundMultimorbidity is increasingly prevalent among ageing patients, leading to reduced daily functioning. To address the challenges posed by multimorbidity in older adults, a person- and context-centred approach is needed. This study aimed to develop a questionnaire as a self-assessment tool for older adults focusing on functioning in general practice based on the International Classification of Functioning, Disability and Health (ICF).MethodsA mixed-methods approach was employed in the development and validation of the German EFA23 (Erfassung Funktionaler Gesundheit im Alter – 23 Fragen; Assessing Functional Health in Old Age – 23 questions) questionnaire. Based on an ICF subset developed in a preparatory phase and consensus study, questionnaire items were formulated and tested in a qualitative pretest, followed by a validation study. A workshop with general practitioners (GPs) was held to develop a supplementary manual for GPs on how to interpret the questionnaire results and discuss them with the patients.ResultsA total of 69 items were developed and tested in the qualitative pretest with 15 respondents, resulting in 37 items for the validation study. The validation study, involving 237 older adults, showed the presence of one significant principal component. It demonstrated good internal consistency (Cronbach’s alpha = 0.967) and construct validity, showing positive correlations with established assessment tools. Descriptive statistics showed differences between the means of self-assessment by patients and an external GP assessment. The final EFA23 questionnaire consists of 23 items assessing limitations in functioning.ConclusionsThe EFA23 questionnaire can be used as a valid self-assessment instrument to measure functioning in older adults, supporting a person- and context-centred approach in general practice.

The effect of education level on depressive symptoms in Chinese older adults–parallel mediating effects of economic security level and subjective memory ability

BackgroundDepression in older adults needs urgent attention. Increased education level may reduce depressive symptoms in older adults, and that economic security level and subjective memory ability may also have an impact on depressive symptoms in older adults, but the mechanisms between education level and depressive symptoms in older adults are unclear. This study endeavors to investigate the parallel mediating roles of economic security level and subjective memory ability between education level and depressive symptoms in older adults.MethodsA total of 4325 older adults people aged 60 years and above were selected from the China Family Panel Studies (CFPS) as the study population, and all data were analyzed using SPSS 25.0 software. Spearman correlation analysis was used to explore the correlation between the variables. Model 4 from the SPSS macro was used to assess the parallel mediating role of economic security level and subjective memory ability in the relationship between education level and depressive symptoms in older adults.ResultsEducation level, economic security level, and subjective memory ability were significantly associated with depressive symptoms in older adults (p < 0.01). Educational level was a negative predictor of depressive symptoms (β=-0.134, P < 0.001). Education level was a positive predictor of economic security level (β = 0.467, P < 0.001) and subjective memory ability (β = 0.224, P < 0.001). Education level, economic security level, and subjective memory ability were significant negative predictors of depressive symptoms (β= -0.039, P < 0.05; β= -0.122, P < 0.001; β= -0.169, P < 0.001). Education level influenced depressive symptoms through parallel mediating effects of economic security level and subjective memory ability, with mediating effects accounting for 42.70% and 28.30% of the total effect, respectively.ConclusionsEducation level not only directly influences depressive symptoms in older adults, but also indirectly through the economic security level and subjective memory ability. Educational level can reduce depressive symptoms in older adults by increasing their economic security level and enhancing their subjective memory ability. The findings of this study emphasize the importance of improving the educational level of the population as it affects people’s mental health in old age.

A Look at Primary and Secondary Prevention in the Elderly: The Two Sides of the Same Coin.

The global population is experiencing an aging trend; however, this increased longevity is not necessarily accompanied by improved health in older age. A significant consequence of this demographic shift is the rising prevalence of multiple chronic illnesses, posing challenges to healthcare systems worldwide. Aging is a major risk factor for multimorbidity, which marks a progressive decline in resilience and a dysregulation of multisystem homeostasis. Cardiovascular risk factors, along with aging and comorbidities, play a critical role in the development of heart disease. Among comorbidities, age itself stands out as one of the most significant risk factors for cardiovascular disease, with its prevalence and incidence notably increasing in the elderly population. However, elderly individuals, especially those who are frail and have multiple comorbidities, are under-represented in primary and secondary prevention trials aimed at addressing traditional cardiovascular risk factors, such as hypercholesterolemia, diabetes mellitus, and hypertension. There are concerns regarding the optimal intensity of treatment, taking into account tolerability and the risk of drug interactions. Additionally, uncertainty persists regarding therapeutic targets across different age groups. This article provides an overview of the relationship between aging and cardiovascular disease, highlighting various cardiovascular prevention issues in the elderly population.

Social relationships and their association with the functional capacity of older Chilean adults: longitudinal evidence

BackgroundFunctional capacity is recognized as a central factor for health in old age and not all studies that seek to clarify the role of social relationships in functional capacity are conclusive. The subject has only been studied in a limited way in Latin America, a region that is aging prematurely, with evidence primarily from developed countries, which have experienced a more gradual aging of their population. This longitudinal study aimed to determine how aspects of social relationships impact the functionality of older Chileans.MethodologyWe conducted a cohort study of 2,265 people aged 60 years or older who lived in the community and resided in Greater Santiago, Chile. Five aspects of social relationships were considered at baseline (participation in groups, clubs, or organizations; number of people in the household; participation in recreational activities; perception of material support, help or advice, and marital status), from which a cluster analysis by conglomerate was performed and used as the exposure of interest. Functional limitation (FL) was the dependent variable, classified as a limitation in at least 1 basic activity of daily living or 1 instrumental activity or 2 advanced activities. The control variables considered were: sex, age, educational level, multimorbidity, depression and years of follow-up. Survival analyses using a Cox proportional hazard regression and multilevel logistic regressions (person level and follow-up wave level) were performed.ResultsThe identified clusters were four: “without social participation and does not live alone”; “without a partner and without social participation”; “no perception of support and no social participation”; “with participation, partner and perception of support”. Social relationship clusters predicted FL incidence and FL reporting during follow-up. Being in the clusters "without social participation and does not live alone" and "without partner and without social participation" were risk factors for incident FL and report of FL during follow-up, compared to being in the reference cluster "with participation, partner and perception of support.ConclusionsIn summary, our study showed that participating in social organizations, not living alone and having a partner are protective factors for presenting and developing functional limitation in old age for community-living Chileans in an urban area.

Religion as a social determinant of health in old age?

ABSTRACT This paper will argue that religion has a special meaning for older adults beyond the findings in the research literature on religion’s effects on health outcomes. Research on religious involvement and health from the past several decades shows a strongly beneficial relationship for persons of all ages, and one that is heightened in old age. Given the pace of secularization, however, the future is uncertain and coming cohorts of older persons may not have the same life course experiences to draw on in late life.

Health in Old Age: Stereotypes and Objective Indicators

Dysfunction of the Murine Liver with Aging and Its Improvement with the Continuous Consumption of Enterococcus faecalis EC-12.

Chronic inflammation is involved in the development of age-related diseases. Given its persistence, controlling chronic inflammation is essential for preventing age-related diseases. In this study, we investigated the effects of Enterococcus faecalis EC-12 (EC-12), which has immunomodulatory and antioxidant effects, on liver gene expression and aging phenomena in mice. Short-term EC-12 administration stimulated the expression of genes involved in lipid synthesis and metabolism in the liver. Furthermore, long-term EC-12 administration from 10 weeks to 1.5 years of age resulted in significant increases in blood interleukin (IL)-6 and IL-10 concentrations (both p < 0.05) and a significant decrease in the monocyte chemotactic protein-1 concentration (p < 0.05). These results indicated pathologic improvement, such as suppression of fat degeneration in the liver. These results suggest that continuous EC-12 intake from a young age can suppress liver function abnormalities, which is one of the aging phenomena in old age, and contribute to health in old age.

Advantageous early-life environments cushion the genetic risk for ischemic heart disease

In one of the first papers on the impact of early-life conditions on individuals' health in older age, Barker and Osmond [Lancet, 327, 1077-1081 (1986)] show a strong positive relationship between infant mortality rates in the 1920s and ischemic heart disease in the 1970s. We merge historical data on infant mortality rates to 370,000 individual records in the UK Biobank using information on local area and year of birth. We replicate the association between the early-life infant mortality rate and later-life ischemic heart disease in our sample. We then go "beyond Barker," by showing considerable genetic heterogeneity in this association that is robust to within-area as well as within-family analyses. We find no association between the polygenic index and heart disease in areas with the lowest infant mortality rates, but a strong positive relationship in areas characterized by high infant mortality. These findings suggest that advantageous environments can cushion one's genetic disease risk.

Childhood adversities and memory function in later life: the mediating role of activity participation

BackgroundChildhood adversities may lead to decreased activity participation in later life, impacting memory health in ageing adults. Childhood adversities related to deprivation and threat, as conceptualized by the Dimensional Model of Adversity, can exhibit distinct impacts on cognitive and emotional outcomes in children and younger adults. This study examined the potential influence of childhood deprivation and threat on memory function in later life and the mediating role of activity participation in these relationships.MethodsThis study used data from the first wave of Panel Study of Active Ageing and Society (PAAS), a representative survey of Hong Kong residents aged 50 or above (N = 1,005). Key variables included late-life memory function measured by delayed recall test, deprivation- and threat-related childhood adversities, and the frequency of participation in informal and formal types of activities. Mediation tests were used for analysis.ResultsChildhood deprivation was associated with a lower late-life memory function, whereas threat was not. The negative effects of childhood deprivation and its subdomain, economic hardship, on memory function were mediated by activity participation. Total participation scores presented the strongest mediating effect (17.3–20.6%), with formal activities playing a more substantial mediating role than informal activities in mitigating the effect of childhood deprivation.ConclusionsThese findings expand the applicability of the Dimensional Model of Adversity to ageing populations, highlighting the influence of deprivation on life-long cognitive development. Furthermore, this study revealed an indirect mechanism by which childhood deprivation affects memory health in old age through diverse activity participation.

Factors associated with malnutrition among older people in Swedish short-term care: Poor oral health, dysphagia and mortality.

To investigate the relationship between malnutrition and potential contributing factors such as poor oral health, dysphagia and mortality among older people in short-term care. This cross-sectional study is a part of the multidisciplinary multicentre project SOFIA (Swallowing function, Oral health and Food Intake in old Age), which includes older people (≥65 years) in 36 short-term care units in five regions of Sweden. Nutritional status was measured with version II of the Minimal Eating Observation and Nutrition Form (MEONF-II), oral health with the Revised Oral Assessment Guide (ROAG), dysphagia with a water swallow test, and the mortality rate was followed for 1 year. Data were analysed using descriptive analysis and logistic regression models to calculate odds ratios for the association between malnutrition and these factors. Among the 391 participants, the median age was 84 years and 53.3% were women. Mortality rate was 25.1% within 1 year in the total group, and was higher among malnourished participants than among their well-nourished counterparts. Severe dysphagia (OR: 6.51, 95% CI: 2.40-17.68), poor oral health (OR: 5.73, 95% CI: 2.33-14.09) and female gender (OR: 2.2, 95% CI: 1.24-3.93) were independently associated with malnutrition. Mortality rate was higher among malnourished people than those who were well nourished. Severe dysphagia, poor oral health and female gender was predictors of malnutrition among older people in short-term care. These health risks should be given more attention in short-term care with early identification.

Milk Fat Globule Membranes for Mental Health across the Human Lifespan.

The milk fat globule membrane (MFGM) contains bioactive proteins, carbohydrates, and lipids. Polar lipids found in the MFGM play a critical role in maintaining cell membrane integrity and neuronal signalling capacity, thereby supporting brain health. This review summarises the literature on the MFGM and its phospholipid constituents for improvement of mental health across three key stages of the human lifespan, i.e., infancy, adulthood, and older age. MFGM supplementation may improve mental health by reducing neuroinflammation and supporting neurotransmitter synthesis through the gut-brain axis. Fortification of infant formula with MFGMs is designed to mimic the composition of breastmilk and optimise early gut and central nervous system development. Early behavioural and emotional development sets the stage for future mental health. In adults, promising results suggest that MFGMs can reduce the negative consequences of situational stress. Preclinical models of age-related cognitive decline suggest a role for the MFGM in supporting brain health in older age and reducing depressive symptoms. While there is preclinical and clinical evidence to support the use of MFGM supplementation for improved mental health, human studies with mental health as the primary target outcome are sparce. Further high-quality clinical trials examining the potential of the MFGM for psychological health improvement are important.
